I don't know if this is what you are seeing or not, but I found a bug in the
FreeType2 support code (engine/font_freetype2.c) related to baseline. It
was subtracting from "y" instead of adding (or the other way around - I
forget).
I fixed it to match font_freetype.c (FreeType1) - so they now both work the
same. I don't know if this matches other fonts, but at least all FreeType
code should operate the same.
I'm pretty sure that my changes to font_freetype2.c are in the "patch"
directory on microwindows.org:
ftp://microwindows.censoft.com/pub/microwindows/patch-0.92/
(I think the mods are in "freetype2_changes.zip")
